[ Upstream commit 09d838a457a89883a926b8b0104d575158fd4b92 ]

In ieee80211_lookup_key, the variable named `local` is unused if
compiled without lockdep, getting this warning:

net/mac80211/cfg.c: In function ‘ieee80211_lookup_key’:
net/mac80211/cfg.c:542:26: error: unused variable ‘local’ [-Werror=unused-variable]
struct ieee80211_local *local = sdata->local;
^~~~~

Fix it with __maybe_unused.
